first embodiment
[0030]The first embodiment is described hereinafter with reference to FIGS. 1-3.
[0031]As seen in FIG. 1, a retaining device 1 enables the temporary retention of a boot, not shown, on a board 2.
[0032]In a known manner, the retaining device 1 has a base 3 having the general form of a plate, which extends longitudinally between a rear end 4 and a front end 5.
[0033]The base 3 has an upper surface 6 provided to be on the side of the boot, i.e., facing the boot, and a bottom surface 7 provided to be on the side of the board 2, i.e., facing the board.
[0034]A rear pad 8 and a front pad 9 are provided to absorb board steering forces. The pads are located in the area of the rear end 4 and the front end 5, respectively. However, one could alternatively use a single pad that extends along the base, or yet other additional pads.
[0035]One can also provide not to use a pad, the boot taking support directly on the base 3 in such case.
[0036]The base 3 is secured to the board 2 by an anchoring mechan...
second embodiment
[0092]For the second embodiment, as seen in FIG. 4, the base 160 of a retaining device has a top surface 161 opposite a bottom surface 162. The base 160 is transversely bordered with a lateral flange 163 and a medial flange 164. The base 160 has a core 165 that supports ribs such as those designated by the reference numerals 166, 167. Cavities, such as those designated by the reference numerals 168, 169, are formed between the ribs.
[0093]In comparison with the first embodiment, the ribs and the cavities, in the second embodiment, are on the side of the top surface 161, i.e., toward the boot. The core 165 is therefore turned toward the board. Thus, the center of gravity of the base 160, and therefore of the device, is lowered. Moreover, the core 165 is biased in traction when the base 160 tends to bend due to traction on a linkage / strap. When the core works in traction, it opposes a greater mechanical resistance. This improves the stiffness of the base 160.
[0094]In a non-limiting man...
third embodiment
[0095]the invention is described with reference to FIG. 5.
[0096]A retaining device 180 has a base 181 that is bordered transversely by a lateral flange 182 and a medial flange 183. An arch 184, shown elevated from the base and rearward of the rear support element, connects the flanges 182, 183 to one another toward the rear of the device. Here, the base 181, the flanges 182, 183 and the arch 184 form a unitary / one-piece element made, for example, of a plastic material. However, one can provide that the arch be affixed to the flanges by any means, such as by means of screws.
[0097]Generally speaking, the invention is constructed from materials and according to implementation techniques that are known to one with ordinary skill in the art.
[0098]The invention makes it possible to optimize the quantity of material necessary for the manufacture, and to use low density and low cost materials, such as polycarbonates or polyamides.
[0099]The invention is not limited to particulars of the deta...
